For the third time, specialists from all over the world met to present their most recent scientific results and to update their knowledge in the expand ing field of nutrition and, osteoporosis. Major nutrition-al factors, such as calcium and vitamin D, were reexamined, with special attention on the ef fects of calcium, given either as a supplement or in dairy products in chil dren and adolescents, and to vitamin D supplementation in the elderly. The RDA for calcium was questioned, and the calcium requirement was rede fined. Special attention was paid to proteins and their growth promoting action via IGF-l, as well as to the profound effects on calcium and bone metabolism of vegetarian diets or diets rich in acidic or alkaline foods. Although considered an environmental factor influencing the pathogenesis of osteoporosis, nutrition was discussed in relation to genetic conditions, because certain genetic conditions modifY patients' responses to nutritional deficiencies and to supplementary interventions. These proceedings report the wide spectrum of research currently being undertaken and the new perspectives this presents and emphasize the sig nificant and important impact of nutrition on bone health and disease.

Calcium in Humana Health provides up-to-date research on calcium function and its relationship to health. Among the topics discussed in this text are calcium function as the main element in bone as a stabilizer of proteins, the methodology for estimating calcium intakes of various populations as well as how to conduct controlled feeding studies, homeostasis, as well as calcium intakes, requirements, and dietary sources of calcium. This critical resource of calcium in human health is a must have for health professionals, researchers, and students alike.

This comprehensive review of the state of our knowledge concerning calcium not only demonstrates its importance to human health, but also defines its many complex roles. The authors summarize the latest basic scientific information on the cellular and metabolic functions of calcium, explaining the leading techniques for accurately measuring its bioavailability, absorption, and kinetics, and showing that calcium deficiency is a major problem while calcium excess a rare one. They also examine the complex regulation of calcium absorption, distribution, and excretion, as well as the multiple interactions of diet/lifestyle, and physical activity in calcium homeostasis. Their discussion of the specific roles of calcium in a variety of clinical disorders-osteoporosis, oral health, obesity, reproductive disorders, and the metabolic syndrome-provides new insights and raises new questions. The complex changes in calcium and phosphate regulation that occur in renal disease and the potential role of calcium in hypertension and vascular disease are also addressed.
